how can I javascript decodeURI in PHP?

Question

I have a javascript which sends some specific information to a PHP api . Before to send it performs encodeURI . How can I "decode" it in PHP ? I understand that urldecode/urlencode is different that javascript encode/decodeURI so what can I use ?

Answer 1

Unless you've encoded it multiple times (e.g. by explicitly calling the encode method AND inserting the value into a form field which is then submitted) you don't need to do anything - it is transparently converted back to its original form when the request is parsed.

Answer 2

Use encodeURIComponent in Javascript: http://www.w3schools.com/jsref/jsref_encodeuricomponent.asp and urldecode in PHP: http://php.net/manual/en/function.urldecode.php

Answer 3

You can use rawurldecode function in php, but this function is not UTF-8, then your have to convert to UTF-8 with utf8_decode like this

echo utf8_decode(rawurldecode('Educa%C3%A7%C3%A3o%20Multim%C3%ADdia'));
